How will Scotland vote on oil and gas policies?

Waving banners, union members chanted “no ban without a plan”.

“We don’t want a repeat of what happened to the miners,” said Unite organiser Claire Peden, adding: “We’re saying no more blank cheques for the Labour Party.

“If they don’t side with workers, don’t side with communities, obviously that funding will fund campaigns like this instead of going to the party.”

Ms Peden says under Labour’s current plans up to 100,000 workers could lose their jobs, including as many as 35,000 in Scotland.

Are such warnings credible?

It depends, says Prof Paul de Leeuw, director of the Energy Transition Institute at Aberdeen’s Robert Gordon University.

He says if there is “no support for the industry” with an immediate halt to all investment then there will be “a massive job impact”.

However, Prof Leeuw adds, that is “unlikely” because “what we will see hopefully is an offset from the renewable sector. One declines, the other one is increasing”.

“We need to get it just right,” he concludes.
